Frequently asked questions
What if my JSON is invalid?
An “Invalid JSON” message appears. Fix the syntax (commas, quotes, braces) and the conversion resumes automatically.
Which types are handled?
Nested objects, arrays, strings, numbers, booleans (true/false) and null. Strings with special characters are quoted.
Is the YAML standard?
Yes, it uses 2-space indentation and block syntax (key: value, “-” for lists), readable by any YAML parser.
Is my data uploaded?
No. The conversion happens entirely in your browser; no content is uploaded.
